   Sammanfattning : To a large extent, organic building blocks are today obtained from petroleum-based products. From an environmental point of view, biomass-derived compounds are more sustainable alternatives to such oil-derived molecules. The 12 principles of green chemistry describe how chemical processes can be improved in terms of sustainability. LÄS MER
